IMPROVEMENT IN JUMP-SEATS FOR CARRIAGES.

Specification forming part of Letters Patent No. 150,354, dated April 23, 1874; application filed March 6, 1874.

To all whom it may concern:

Be it known that I, JOHN J. QUINN, of Columbus, in the county of Burlington and the State of N ew Jersey, have invented a new and useful Improvement in Garriage- Seat-s; and I do hereby declare the following to be a clear and exact description of the nature thereof, sufficient to enable others skilled in the art'to which my invention appertailns to fully understand, make, and use the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figuresl and 2 are side elevations of the device embodying my invention. Fig. 3 is a rear view thereof'.

Similar letters of reference indicate like parts in the several gures.

This invention relates to improvement in jump-seats; and consists in so connecting the upper ends of the hinged legs of the seats that said seats may be readily moved or jumped byoperation on their sides wit-hout liability of binding or catching, and without necessitating operation at the middle of the seats. It also consists in arms rigidly connected to one pair of the legs of the rear seat and bearing solidly against the other pair of said legs, so that the joints between the legs and seats are relieved, the legs are strengthened, and the seat is firmly supported. It also consists in arms hinged to one pair of the legs of the front seat, and adapted to bear solidly against the other pair of said legs, and also engage with notches on the under side of the scat for strengthening the supports of the seat and holding said seat at various heights. e

Referring to the drawings, A A represent the front and back seats of a carriage or vehicle, which may be of well-known form and construction. These seats are supported upon legs B B in pairs and series, whose upper ends are jointed thereto, and the lower ends are jointed to proper portions of the body C of the carriage. D represents bars which extend transversely under the seats and are connected to the upper ends of the legs B B at or about the respective axes G thereof, so that a leg, B, at'one side of the carriage and the respective leg B at the opposite side are continuous of each other by means of one of the bars D,

whereby said legs and bar move as one. To one or both of the legs of the pairs B B of the rear seat there are rigidly connected arms H, which project from said legs toward the legs B of the adjacent series, so as to engage therewith. rIo one or both of the legs ofthe pairs B B of the front seat there are jointed arms J, which project from said legs toward the legs B of the adjacent series, so as to engage therewith, and are adapted to beswung upwardly in order to engage with notches K K, formed in the lower side of the seat A, or the frame thereof.

v The operation is as follows: Vhen the front seat is not required the arms J are swung up so as not to engage with the legs B, and the seat is moved to the rear to its full extent. The back seat is now moved to the front, so

as to come over the front seat, whereby the latter is out of way and a single seat is serviceable, as seen in Fig. l. When both the front and back seats are required, they may be made to assume various positions, as shown in Fig. 2. rEhe back seat may be moved entirely to the rear, and the front seat entirely to the front, or the back seat may be moved forward to its full extent, and the front seat be made to assume intermediate positions. It will be seen that when a seat is taken hold of in order to move or jump it, the bar D connecting the relative legs B atopposite sides, causes a simultaneous motion of both legs, said legs and bar moving as one, whereby there will be no catching or binding of the joints of the movable portions, and it will not be necessary to reach to the middle of the seat in order to impart the desired motions to the seat, which defects otherwise occurring are sources of serious trouble and inconvenience. The arms H moving with the legs B in either the forward or backward motions of the seat, come in contact with the adjacent legs B and brace the supports for the seat, the strain on the legs being taken from the joints and diffused over the lengths of the legs. The arms J possess similar features, and in addition thereto they may be moved to engage with the notches K on the under side of the front seat and thus support the latter in its various heights, the manifold adjustment of said front seat being desirable, for children as Well as adults may require to occupy the same and face the front or rear of the carriage7 for purposes Well known.

I am aware that jump seats have had their legs strengthened by intermediate arms; such features are therefore not claimed broadly.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, With a jump-seat7 of the hinged supporting-legs B and a connectingbar, D, to operate substantially as and for the purpose set forth.

2. The combination, with the pair of legs B B and rear seat A, of the arms Hrigidly connected to one pair of said legs and bearing against the other pair thereof, substantially as and for the purpose set forth.

3. The hinged arm or arms J in combination with legs B B of the notched jump-seat, substantially as and for the purpose set forth.
